Improvements in epidermal function prevent relapse of psoriasis: a self‐controlled study

While therapeutic approaches for psoriasis are widely available, preventive regimens are lacking. We aimed to determine whether improvements in epidermal function could prevent psoriasis relapse. Two self‐controlled cohort studies were designed, enrolling two cohorts of patients with psoriasis (n = 30 and n = 60) to be treated topically with an in‐house‐prepared emollient or ATOPALM^® cream applied twice daily to one forearm for 20 and 30 days, respectively, while the same sites on the contralateral arm served as the untreated control. Epidermal function on both arms was assessed prior to and at the end of the trials. Delayed relapse on the treated arm was seen in 54.5% and 71% of patients in the first and second cohort, respectively. The time of psoriatic relapse correlated with the extent of abnormalities in baseline epidermal function. These results suggest that improvements in epidermal function with topical emollients can prevent/attenuate the development of psoriasis.     

经胫骨隧道前交叉韧带双束八股解剖重建的临床研究

目的观察关节镜下采用自体腘绳肌腱经胫骨隧道前交叉韧带（anterior cruciate ligament, ACL）双束八股解剖重建的临床效果。方法随访上海交通大学附属第六人民医院运动医学科2018年12月—2020年1月收治的103例ACL断裂患者资料，其中男78例，女25例，年龄18~45岁，平均（26.8±5.86）岁；左侧47例，右侧56例，均采用关节镜下自体腘绳肌腱经胫骨隧道打股骨骨隧道，ACL双束八股解剖重建。按照Lysholm评分、国际膝关节评分委员会（IKDC）膝关节评分、Tegner膝关节评分标准和膝关节自我效能量表K-SES评价疗效。结果所有患者术后获随访12～42个月，平均（24±8.18）个月；手术前、末次随访评分比较，Lysholm评分分别为（48.41±4.44）分和（95.34±1.91）分，2组比较差异有统计学意义（P<0.001)；IKDC评分分别为（44.05±4.36）分和（95.66±1.89）分，2组比较差异有统计学意义（P<0.001)；Tegner评分分别为（2.84±0.95）分和（6.15±0.89）分，2组比较差异有统计学意义（P<0.001)；膝关节自我效能量表K-SES量表（3.10±0.83）分和（7.12±1.10）分，2组比较差异有统计学意义（P<0.001)。末次随访103例患者前抽屉试验阴性，轴移试验阴性。98例（95.1%）Lachman试验阴性，5例（4.9%）Lachman试验1°阳性。结论关节镜下采用自体腘绳肌腱经胫骨隧道双束八股解剖重建前交叉韧带是一种恢复膝关节稳定性，恢复伤前活动水平的有效方法。     

HBV患者血清YKL-40、CA19-9、GP73水平与其病情相关性

目的 分析HBV患者YKL-40、CA19-9、GP73水平差异及与患者病情轻重程度的相关性,探讨HBV患者病情的判定指标。方法 选取2015年5月—2018年5月收治的100例HBV患者,其中慢性HBV感染组40例、慢性乙型肝炎组36例、HBV相关肝硬化组24例,同期选择我院健康体检的健康者50例作为健康对照组;检测患者血中YKL-40、CA19-9、GP73水平;分析HBV感染患者血清YKL-40、CA19-9、GP73水平与病情轻重程度的相关性。结果 慢性HBV感染、慢性乙型肝炎及HBV相关肝硬化患者血中YKL-40水平分别为（36.38±4.19）ng/mL 、（49.02±4.32）ng/mL、（65.14±5.21）ng/mL ,CA19-9分别为（12.03±1.03）KU/L、（13.84±0.98）KU/L、（16.94±0.81）KU/L,GP73分别为（47.22±5.38）ng/mL 、（98.53±10.24）ng/mL 、（229.85±12.19）ng/mL,均明显高于对照组的（28.19±3.27）ng/mL 、（7.34±0.92）KU/L 、（30.93±3.89）ng/mL,均P=0.000 0。随着慢性HBV感染者、慢性乙型肝炎患者和不同HBV相关肝硬化患者肝脏炎症及纤维化程度加重,患者血中YKL-40、CA19-9和GP73也随之显著增加,均P=0.000 0;YKL-40、CA19-9和GP73均是影响HBV感染患者体内炎症坏死及肝脏纤维化的独立性影响因素,差异有统计学意义（P<0.05）。结论 HBV感染患者血清中YKL-40、CA19-9、GP73水平是HBV感染患者病情轻重程度的独立性影响因素。     

Utility of the 3‐Vessel and 3‐Vessel and Trachea Views in Prenatal Diagnosis of a Pulmonary Artery Sling

A pulmonary artery (PA) sling is a very rare congenital cardiovascular anomaly, and only a few studies have reported PA slings in fetuses. The relationship of the PA, aorta, ductus arteriosus, and trachea can be evaluated in the 3‐vessel and 3‐vessel and trachea views during fetal echocardiography. A PA sling can be detected by abnormal positioning of the left PA in relation to the trachea when sweeping from the 3‐vessel view cranially to the 3‐vessel and trachea view. Here we report 3 cases of fetal PA slings and their follow‐ups. Two cases were confirmed by postnatal echocardiography, and the other case was confirmed by a cardiovascular cast after pregnancy termination. We emphasize that the 3‐vessel and 3‐vessel and trachea views are of crucial importance in the prenatal diagnosis of a PA sling.
